Abstract
An image display device having an electro-optical medium interposed between a pair of electrode substrates composing a matrix electrode, a driving circuit for driving the electro-optical medium by selectively applying a voltage on the matrix electrode and a reference voltage generator for supplying the driving circuit with a predetermined driving voltage. A noise compensating circuit is interposed between the driving circuit and the reference voltage generator, the noise compensating circuit detecting a noise in a voltage supplied from the reference voltage generator to the electro-optical medium at a predetermined noise detecting position, forming a noise compensating voltage having a first polarity reverse to a second polarity of the noise by using the noise, and supplying the noise compensating voltage to the driving circuit.
